Detected bus errors
Here, the number of detected bus errors is displayed. If this counter is not equal 0, the cabling should be
checked (provided that no PROFIBUS connectors were pulled or inserted - usually there are short bus
disturbances during pulling or inserting of PROFIBUS connectors).
CycleWithRepeatCounter
Here, the number of PROFIBUS cycles is displayed, in which a telegram was repeated at least once.
Repetitions indicate that there is something wrong with the bus physics.
Max. repeat/cycle
Here, the maximum number of repetitions within a cycle is displayed.
min./max./actual cycle time
Here, the minimum, maximum and current DP cycle time is displayed. Only those cycles are considered,
during which all slaves participated in the data exchange and no repetitions occurred.
CycleWithNoDxch counter
Increments if not all slaves participate in the data exchange (i.e. have a DpState not equal 0).
Output-Failed-Cycle-Counter
Increments if the DP cycle was not complete before the next EtherCAT cycle (EL) started and all slaves are
in data exchange (i.e. they have a DpState of 0).

Box states tab
Fig. 93: Box states tab
Here, an overview of all current box states, the Repeat counter (increments for each telegram repeat to the
slave) and the NoAnswer counter (increments every time the slave fails to answer) is displayed.
